OVERHEAD HOlsTiNG AND CARRYING DEVICE.

SPECIFICATION forming' part o f Letters Patent N o. 664,622, dated December 25, 1900.

Application filed September 14, 1900. Serial No. 30,018. (No model.) I

To a/ZZ whom, it may concern:

Be it known that I, NORMAN E. BROWN, a citizen of the United States, and a resident of St. Joseph, in the county'of Berrien and State of Michigan, have invented `a new and Improved Overhead Hoisting and Carrying Device, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved overhead hoisting and carrying device which is simple and durable in construction and arranged to 'permit of quickly and safely raising a load, locking the same in position, and then transferring the same overhead to a distant place.

The invention consists of novel features and parts and combinations of the same, as

will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specication, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the improvement with the drivingshaft in section and parts in dotted lines. Fig. 2 is a plan view of the same. Fig. 3 isa side elevation of the same with parts in a diifereut position, and Fig. et is a transverse section of the improvement on the line 4 4 in Fig. l.

A carriage A, of any approved construction and provided with wheels B, is mounted to travel on an overhead track O, and in the frame of the carriage are mounted to turn disks D, attached to a lever E, under the control of the operator, for simultaneously turning the disks D in their bearings. In the said disks D is journaled eccentrically a shaft F, carrying a friction-wheel G, and on said shaft are also secured sprocket- Wheels H, over which pass hoisting chains or ropes I, extending over guide-pulleys J J, a hook I beingon one end of the chain and a weight l2 on the other end, so as to prevent slack in the chain during the time the load is hoisted. The Wheel G is adapted to be moved bodily in engagement With the peripheral surface of a driving-pulley K, secured on a driving-shaft L, journaled in suitable bearings attached to one end of the overhead track C. On the shaft L is secured 'a pulley L, connected by belt with other machinery, so that a rotary motion is given to the shaft'L and the pulley K secured thereOn`.`

When the several parts are in the position shown in Figs. l and 2 and the carriage Aisr at one end of the track Gand the operator has thrown the lever E into a vertical position, then the wheel G is in contact with the driving-pulley K, so that the wheel G is rotated, and consequently the shaft F, with the wheels H, to impart a traveling motion to the hoisting-chains I, so that the load hung on the hook I is hoisted. r In order to lock the Wheel G iu frictional contact with the lpulley K, spools N are provided and mounted to rotate loosely on the shaft L, said spools being engaged by the inclined ends E of arms E2, projecting from the lever E, so that when the latter is thrown into a vertical position the said ends E engage the spools and hold the wheel G in frictional Contact with the pulley K. By making the ends E with inclines it is evident that the Wheel can always be drawn in firm contact with the pulley K, even if the said wheel and pulley are reduced in size by wear. It is understood that when the ends E of the arms E2 move in engagement with the spools N then the carriage A is drawn to the left to. bring the Wheel G in firm frictional contact with the pulley K. When the load* has been hoisted, then the operator throws the lever E to the right to turn the disks D and move the wheel G out of frictional contact with the pulley K and to move it in frictional engagement with a friction-block O, carried by the frame of the carriage A. When this takes place, the wheel G is locked against rotation, so that the hoisting-chain I, with its load, remains stationary, and the carriage can now be moved along the track C to a distant place with the load and without danger of the load descending, owing to the locked position of the wheel G on the friction-block O.

When the carriage has been moved the desired distance and it is desired to lower the load, then the operator manipulates the lever E correspondingly by throwing the same gradually to the left `to allow the AWheel G to rotate and the `chain I to travel with the vload descending and thefriction-bloek 'O used as a brake to preventv a too-rapid descent of .the load.

Having thus fully ,desoribed my in.Vonii/,10.11a i I claim as ,new and desire to secure by Letters Patent- 1. An overhead hoisting and carrying device, eomprisingaearriage mounted to travel, a driven shaft haying a .driving-pulley, joui?- naled in stationary bearings, a wheel on said carriage adapted to be geared with said pulley and controlling a hoisting chain or rope,

a xed friction-block carried by said carriage,

and moans for bodily moving said wheel lin engagement with either the said dri ving-pnlieyor the said frietion-blook,said means being arranged .to look the Wheel .and piilley in position when thro-wil ,in gear, said .meansfbeing also arranged. to compensate for any wear 0a the wheel and pulley to hold the latter ia friotional oontaet, as set forth.-
